将固体熔融法合成的2,3,9,10,16,17,23,24-八羧基酞菁铁(FePc(COOH)_8)敏化二氧化钛制备了酞菁铁二氧化钛催化剂。通过UV、FIIR、PL、XRD、DRS、XPS和N2吸附-脱附等一系列实验方法对催化剂进行了表征和催化性能分析。在可见光条件下研究了八羧基酞菁铁(FePc(COOH)_8)敏化的TiO_2催化剂对亚甲基蓝(MB)、罗丹明B(RB)、中性红(NR)、酸性红(AR)和孔雀石绿(MG)水溶液的降解动力学。研究结果表明在t=100min时,此光催化剂降解这四种有机染料均有良好的效果。染料降解动力学曲线拟合表明此光催化降解过程符合一级化学反应动力学方程,其降解MB、RB、NR、AR和MG动力学常数分别为0.04359、0.03508、0.01901、0.01302 min~(-1)和0.00968min~(-1)。
Iron phthalocyanine titania was prepared by sensitizing titania with 2,3,9,10,16,17,23,24-octa carboxyphthalocyanine (FePc (COOH) _8) synthesized by solid melting method. The catalysts were characterized and characterized by a series of experimental methods such as UV, FIIR, PL, XRD, DRS, XPS and N2 adsorption-desorption. The effects of FePc (COOH) _8) sensitized TiO_2 catalysts on the degradation of methylene blue (MB), rhodamine B (RB), neutral red (NR), acid red Degradation Kinetics of Stone Green (MG) Aqueous Solution. The results show that at t = 100min, the photocatalyst degradation of these four organic dyes have good results. The curve of dye degradation kinetics showed that the photocatalytic degradation was in accordance with the first-order kinetic equation. The kinetic constants of degradation of MB, RB, NR, AR and MG were 0.04359,0.03508,0.01901,0.01302min ~ (-1) ) And 0.00968min ~ (-1).
